It’s cold, and you have to go to the bathroom before bed…is this you?

I drink very little water in the winter, but I always feel like going to the bathroom? I just went to the bathroom before going to bed, and after finally warming up the bed, I have to go to the bathroom again before going to sleep... Why is this happening?

Why do I urinate frequently when the weather gets cold?

Is it because you don’t sweat?

Obviously, the answer is not that simple!

In fact, the saying that frequent urination occurs when the weather gets cold is not entirely correct . Rather, it is a sudden drop in temperature that causes frequent urination .

We are warm-blooded animals, and are extremely sensitive to changes in ambient temperature. Even if the temperature does not change much, we have to adjust in time to maintain our body temperature. However, when the temperature drops suddenly, the blood vessels in the skin will contract, blood pressure will rise, and the human body will produce antidiuretic hormone , which is mainly responsible for frequent and infrequent urination.

If you do not drink water for a long time or sweat a lot, it will stimulate the increase of antidiuretic hormone and reduce urine volume.

On the contrary, when the weather gets cold, the secretion of antidiuretic hormone will be inhibited and urine production will increase.

In addition, the cold will directly stimulate the receptors on the skin, resulting in a decrease in bladder capacity and frequent urination . It is not just the low temperature that will cause stimulation, but even touching cold objects will do the same.

You must go to the toilet before going to bed.

What else to say?

Then you may be the legendary "pee sleeping body".

The urinary sleep body refers to a physique that requires a trip to the toilet before going to bed, otherwise you cannot fall asleep. If you do not go to the toilet, you will toss and turn in bed for a long time, and even if you come back from the toilet and play with your phone for a while, you still have to go to the toilet before going to bed.

Oh, this is exactly what I am talking about! Someone added that after peeing, I have to drink some water before going to bed... I am also very sleepy and tired, so I put down my phone and go to the toilet again to wake up.

Who understands? The bed is finally warm in winter, but before going to bed, you have to muster up the courage to get out of the bed to pee, and when you come back, everything is "cold"! Is "urinary sleeping body" a common phenomenon, or is it a "problem"?

Don't worry, there is no such thing as "urinary body" in medicine. Generally speaking, there are three reasons why you always want to go to the toilet before going to bed:

1. The urine volume before bedtime has reached the amount that causes the urge to urinate. Usually, the bladder capacity of an adult is 350-500ml. When the urine volume reaches 150-250ml, the urge to urinate begins to appear. Drinking water before bedtime, taking diuretics, etc. can cause the urge to urinate before bedtime.

2. Bladder hypersensitivity Some people have sensitive bladders. When there is only a small amount of urine accumulated in the bladder, they will feel the urge to urinate, and then they need to go to the toilet to relieve the urge.

3. Neurological factors or habit problems Some people develop the habit of urinating before going to bed to avoid getting up at night, and this behavior becomes a conditioned reflex. In addition, psychological effects such as tension, anxiety, and stress can also cause psychological urination disorders. For example, giving a speech/performance on stage before an exam, taking a long-distance bus, etc., are basically psychological urinary frequency. Often at this time, the urge to urinate jumps wildly, and the presence of urine is fierce, but the amount of urine is very small.

In other words, most people's "want to pee before going to bed" is actually just a psychological effect or a habit. In particular, many people may have been accustomed to peeing before going to bed since childhood or school. Now, this action has become part of life habits.

Is there any hope for people with sleep-wetting body?

Although there is nothing wrong with your body, "running to the toilet at critical moments" can sometimes be quite frustrating. Many people are also wondering how to solve this problem.

Psychological problems must be addressed from a psychological perspective. Here are three recommended approaches:

1. Believe in yourself

You can use psychological suggestion and tell yourself: My bladder can hold more than I thought, this little bit of urine is not a small matter, I can hold it.

2. Enhance sense of security

Control in advance and drink less water. Control your water intake before going to bed and change your drinking time from before going to bed to after waking up. If you drink less water, you will naturally not want to pee!

3. Let it flow

Don't worry about it. Don't associate peeing with other things. Just go if you want to, and relax. As long as you can sleep, it's just a few more trips to the bathroom, which is not a big deal.

Of course, if you want to improve the problem of wanting to urinate before going to bed, you can drink less water before going to bed, relax your mind, and maintain a good mental state.

It should be noted that if you interrupt your sleep twice or more in one night because of the strong urge to urinate, it is considered frequent. Generally, when you reach this state, you will feel troubled. This is not sleep urination, but may be nocturia. Diseases such as urinary tract infection, hyperthyroidism, diabetes, prostate hyperplasia, etc. may cause excessive nocturia.

If you are troubled by nocturia, do not rely on searching the Internet to diagnose the condition yourself. Go to the urology department of a regular hospital, register , ask a doctor to examine you, and prescribe the right medicine.
